Flooring Rubber Flooring Manufacturers of rubber flooring may include: Amtico and Johnsonite. Check your manufacturer’s website for specific cleaning instructions. First Cleaning After Commercial Installation - After installation, wait 48 hours before proceeding with the stripping. During manufacturing this product is covered with a releasing agent. This releasing agent MUST be removed. - To remove the releasing agent, use a polisher (150 to 175 R.P.M.) with fiber or nylon . Prepare a mixture such as Blue Label and water (5 cups Blue Label per 4.5 litres of warm or cold water). Spread it evenly over the floor and wait 15 to 20 minutes before proceeding with the stripping. - Once this is completely done, use a vacuum or a to absorb the residue. - Rinse with a solution of cold water and ordinary vinegar (1 ounce of vinegar per 4.5 litres of water.) Use a vacuum or mop to absorb the water. IMPORTANT: If the first stripping is not done correctly the releasing agent will remain on the floor and the subsequent coats of sealer will not adhere. - Apply two thin coats of sealer such as “Platinum Label” with a or waxing mop. Let dry before applying a second coat. - Proceed to spray buff with a solution such as Platinum Label 20 % and 80 % cold water into a vaporizer. Use a polisher (175 R.P.M.) with a fiber of nylon . Regular Routine Cleaning - Remove surface dust and soil particles by daily sweeping or vacuuming. If necessary, clean with a wet mop, using floor a cleaner such as Green Label (follow instructions on label). Do not use powder of high- sudsing detergent. For heavily soiled floors, proceed to spray buff using a mixture such as Green Label 20% and 80% cold water in a vaporizer. Clean with a fiber or nylon brush or an autoscouring machine equipped with washing brushes. - Then proceed to spray buff with a solution such as Platinum Label 20 % and 80 % cold water into a vaporizer. Use a polisher (175 R.P.M.) with a fiber of nylon brush. Some rubber flooring contains built-in waxes. The more the floor is buffed, the better the appearance. If a high gloss is desired apply floor finish such as Silver Label at full strength which will give the rubber flooring a brighter sheen than its normal wax finish. - Hard-set finishes will scratch or powder under heavy traffic. A thorough cleaning and stripping is necessary for the acrylic finish such as Silver Label to bond with the tile surface. These care recommendations are provided as assistance only. We do not assume responsibility for actual work performed. Periodic Deep Cleaning - If the floor must be thoroughly cleaned, follow the recommendations given under “First Cleaning” section First Cleaning After Commercial Installation Precautions - To avoid scratches, do not clean with floor pads or any other industrial equipment. - Do not apply thick coats of sealer. Ensure that the tile surface is completely protected by the sealer. - To spread the sealer, use an applicator, preferably a roller or mop. - Do not operate machine over 175 R.P.M. Do not use high speed machines on rubber floorings. - Further technical information may be obtained from your rubber flooring manufacturer.

Vinyl Tile & Vinyl Sheet Floors Check your manufacturer’s website for specific cleaning instructions. Initial Maintenance after Installation: - Sweep or vacuum floor thoroughly. - Damp mop with a solution of a neutral detergent such as Armstrong S-485 Floor Cleaner carefully wiping up black marks, etc. - Apply two coats of a high quality commercial floor polish such as Armstrong S-480 Floor Polish - Do not wash the floor for at least four to five days after installation (prevents excess moisture from interfering with adhesion) Preparation of Vinyl Composition Tile - Five or more days after installation, scrub the floor using a neutral detergent such as Armstrong S-485 Floor Cleaner and a scrubbing pad or brush as recommended for the type of floor being maintained.

NOTE: The use of black or brown pads or their equivalent brushes are not recommended on many vinyl type Floors.

- When the floor is thoroughly cleaned, rinsed and dried, apply three to five coats of a high quality commercial floor polish such as Armstrong S-480 Floor Polish. Certain situations may require the application of one or two coats of sealer. Allow drying time between coats of sealer and/or finish. Do not allow traffic on the floor for several hours (overnight if possible). Preparation Of Vinyl Sheet Flooring - Five or more days after installation, scrub the floor(Medintech and Medintech Tandem must be stripped) using a neutral detergent such as Armstrong S-485 Floor Cleaner and a scrubbing pad or brush as recommended for the type of floor being maintained. NOTE: The use of black or brown pads or their equivalent brushes are not recommended on many vinyl Floors. NOTE: If the floor is badly soiled or scratched, strip it using the same procedure but substitute a high quality floor stripper such as Armstrong S-490 Floor stripper and a stripping pad or brush as recommended for the type of floor being maintained. - When the floor is thoroughly scrubbed or stripped, rinsed and dried, apply three to five coats of a high quality floor polish such as Armstrong S-480 Floor Polish (may be preceded by one or two coats of sealer), allowing ample drying time between coats. Do not allow traffic on the floor for several hours (overnight if possible). Continuing Regular Maintenance: - Dust mop daily. Removal of gritty dirt is extremely important. Use walk-off mats - Damp mop as necessary with a neutral detergent such as Armstrong S-485 Floor Cleaner. Remove black scuffmarks, chewing gum etc. at this time. - Maintain as flooring type and maintenance system dictates. Spray buffing may be done with a neutral detergent solution such as S-480 Floor Polish.

- As necessary (depending on traffic), apply additional coats of a high quality commercial floor polish such as Armstrong S-480 Floor Polish. This procedure may not be required often if spray buffing is done regularly. Stripping: - When stripping is necessary, follow procedures described above in Preparation for Commercial Use and those found on the label of a high quality floor stripper such as Armstrong S-490 Floor Stripper. - Careful and thorough maintenance by well-trained personnel can significantly reduce the stripping schedule.

NOTE: The use of black or brown pads or their equivalent brushes is not recommended on many vinyl Floors.

NOTE: The use of no-scrub and/or no-rinse strippers is not recommended on tile floors less than two years old because they may affect the adhesive system Stain Prevention - Most staining substances that contact Vinyl resilient flooring can be cleaned up easily. All spills should be removed promptly. A good coating such as Armstrong S-480 Floor Polish will help the floor resist staining and will enhance the floor’s appearance. Polishes can be stripped if staining does occur. Ceramic Tile Regular Cleaning Procedures and Materials, Ordinary Use. - Glazed Tile o Walls: Wipe with a clean, damp cloth or sponge.
